A eet o? Standards 12 rise from the Sides in Fig. 1.

ments therein is a shaft 13, which is disposed above the top of the frame and carries one or more stylographic instruments 14. Each of these instruments, as best shown in Fig. 1()7 comprises a reservoir portion 14a and a nozzle portion 14h extending downward and forward therefrom and provided near its free end with a discharge orilice 14. The portion of the nozzle 14th containing the discharge orifice is intended to rest freely on the top surface of the belting strip a as it passes' over the top portion 9, of the frame, thus leaving a longitudinal line on the surface o'f the str'ip due to the action of the stylograph, as will be readily understood: The marniug of lines made on the belting strip a by the instruments 14: is used principally to determine the lines along which the strip is to be slit, as hereinafter described. One er more of these instruments may be 'used and Vrelatively adjusted as desired, and when any or all of the instruments are not to be. used the inactive instruments have their nozzles tilted to inoperative positionand secured in such tilted position by set-screws 15 engaging the c shaft 13.

lVhen the belting strip a. has been wound upon the spool G, such spool with the material thereon is transferred to the position indicated by the spool 6a, the shaft thereof being mounted in bearing brackets 16 rising from the left end of the frame, as shown g Disposed over the end portion of the frame 1,. adjacent to the spool G are two sets of opposing feed-rolls 17, 17 and an interposed set of cutter-wheel carryingshafts 18, on which latter are mounted one or more sets Vof enacting cutter-wheels 19. The lower one of each of feed-rolls 17 has its shaft ends journaled in bearing-blocks 20, while the upper roll of each set is yieldingly urgeil toward the lower roll by springs 21., which bear downward upon bearingblocks 22 in which the shaft ends of the upper roll are mounted. The bearingbloeks 2O and 22 of each set are carried by standards 23 rising from the frame sides, and the shafts 18 are. journaled at their ends in standards 24 rising from the frame. Tables 25 are disposed between the cutter- 'disks 19 and the respective sides of the feedrolls 17, 17 in the plane of bite of the rolls and the cutter-disks. and support the belt strip in its passage between the feed-roll sets and the cutter-disks. The belting strip a after passing through the first set of feedrolls 17 and being slit into two or more lengths or filler-strips by the cutter knives 19, thence passes between the second set of rolls 17 and the strips Z) are wound upon registering spools QG carried by a shaft that is journaled in bearing standards Q7.

Each of the shafts carrying the different sp`o'ols 2, 6, 6P" and Q16' is composed of a plurality of separable parts to facilitate a removal and placing of spools thereon. One of these shafts is illustrated in detail in Fig. 14, and comprises bearing-lnlshings 28 at the opposite ends thereof for journaling in the respective bearings, such bushings being flanged at their ends to embrace the niarginal edges of the bearings to retain theI bushings therein. lach of these bushings has an axial hole therethrough, which, in the present instance, is square in cross-section, to receive Jche connecting bar Q9 of the shaft, which is projected through one of the bushings and into the other to prevent relative turning of the bushings, and has a handle part or head 3() at one end to facilitate a longitudinal movement of the same relative to the bushings. rlhe spools which are intended to be mounted on the shafts and are of any desired length to suit the width of the belting strips winding thereon or therefrom. are shown, in the present instance, as comprising a barrel or sleeve ineinber 31 carrying flanges 32 atl its outer ends, and also being provided at such ends without the flanges with hub extensions 33 hav` ing openings thcretln'mlgh, whicl are complemental' to the bars Q9, thus causing the spool and its carrying shaft to have rotation in unison.

A. line-shaft 34 is mounted in suitable. bearings i5 at one side of the frame l length-- wise thereof and carries a plurality of axially shiftable bevel-gears for meshing with gears on the adjacent ends of counter-shafts 36, 37. 38, 39 and -l-O, which are iournalcd in suitable bearings transversely of the frame at the left end portion thereof. The gears atl, which drive the respective shafts 36, 38

and 40, are of thc single type, while the gears 49. for driving the shafts 37 and 35) are disposed in connected sets, whereby each set may be shifted to place one or the other gear thereof into driving connection with the associated shaft for imparting forward or reversing rotation thereto as desired. A.

shift-lever -13 is connected with each gear 41 and each of the gear sets 42 to control the shifting movements thereof. T he shaft 36 has sprocket-wheel and chain connection with the shaft carrying spool as shown at 44- in Fig. 1. The shafts 37 and 3S) have similar sprocket-wheel and chain connection, respectively, with the shafts of the lower feet rolls 17 of each set, as shown at 115. The shafts 38 and 40 also have similar sprocketwheel and ,chain connection, respectively, with the lower shaft 18 and the shaft carrying the. spools Q6. as shown at 46.

Bearing standards or frame parts 4:7 risc from opposite sides of the. f `aine 1 forward of the standards 2.7 and are provided with alined sets of bearings in which spool carrying shafts 48 are journaled. The setswof bearings for the shaft lthere shown, in the meente present instance, es being four in number `and arranged in any suitable .manner to '1toeilitate the simultaneous feeding of halting strips from spools mounted on all or s por tion of such shafts it may be desired to ineke belting vcontaining one or more iller stripsE :is hereinafter more full;7 described. Une oi? the shafts the one mounted inthe present instance in the set of bearings 49, is intended to curry :t long the wrapping; strip c of o' holt unwinds, while ythe other shofts are intended to carry spools :2G with the filler strips l) thereon.

hiounted on standards 5l in advance out the standards 47 is n set of 'eedrolls 52, the upper of which serves as :i yielding pres sure roll, while the lower is the drive roll und has ehnin und sprocket-wheel eonneetion :33 with :i subjucent shaft that is journziled in the 't'riune l transversely there on. This shaft has geared connection with the line-shaft 34, the gears of such shaft comprising u pair .35, which are exinlly shiftoble into engagement with one of the other sides of the gear on the shaft and have their movements controlled by :1 shiltlever 56.

The respective stri ps and e. as they feed from n desired number or" the spools 2G und the spool 50, pass together between the set of feed rolls 52 with the filler strips L disposed above und centrally o' the strip o, transversely thereof, und thence into edge .l'olding members 57 disposed in the line oi travel ot the opposite edge portions ot' the strips. The Yfolding members 57 ere mounted for relative troi'lsrerse adjustment on n table 58, which is supported by the standards, l2 at opposite sides of the iframe l. hers 57 are of substantially U-form in crosssection with their open sides facing euch other and gradually converge or approach ene-h other from their receiving to their outlet ends,1 the spoce between the outer edge portions of their inlet ends being substantinll)1 equal to the width ot the Topping strips n while the space between the outlet ends thereof is substantially equal to the vidth ot' the filler strips la. The mouths Ior inlet ends oi' the niemliers 57 are of greater .vertical depth thou the outlet end portions thereof :1nd ure suitably fushioned` :is best shown et 57 in Figs. 2 and to euuse a gradual rollingor folding ot the edge portions ot the strip e over the respective side portions ofthe. filler strips l; with the edges ot the wrapping strip substontiotllyv meeting along; the longitudinal center ot the ller strips, as illustrated in Fipg. 1'1".

Mounted on the table 58 over the forward or outlet end portions of the members 5T is a guide 59 for the overturned eclfes ot the Wrapping' strip o, suoli Ev@guide Y" Tied by inverted ils-hoped Istandi spool 5() from which The memdel which are fixed to the table 58 at the outer sides of the members 57. 4The guide means 5S) is provided in longitudinel alinenient with the longitufglinel'v Center ot' the belt strips b? c with L dependent web 6l, trein the lower edge of which projeet outwardly the opposing l1orizontully-disposed ledge' por As the opj'iosed sideportions of the strip o aire liolded over the respective edge pmtirms of the strip or strips t the edges ol the stri p o are prevented iroin overlapping one another due to projection of such edges over the respective ledges 62 and having Contact with the web The edge folding 4members 5i-57 may be relative y adjusted transverselyv of the table to suit the width of the strips c being en'lployed. such adjustment being; effected by tie projection of retainingu bolts 63 for the members 5T through registering transversely extending slots G4 in the table 'i i Mounted in standards 65 in advance of the outlet end of the edge folding members 57, 5T is :I1 ot' feed-rolls 66, the lower of which hes sproeletnvheel und chain eonneetion GT with e subjscent shtt 68, which has shilitoble trolling such connection. The upper roll 6G of the set is held in yielding' eonction with the drive-roll (io by ineens ot' springs "il, or in any other suitable manner. Cylinder 72 is carried for tree rotation by arms 73 projecting rearwardly 'from e shaft 74, which is mounted ot its ends in bee'rinfr standards G5. The cylinder 72 is intende to rest freely upon the belting between its point of emergence lrozn the folding inem` hers 5l und the of feed-rolls G6 and to stomp an identifying' niark on the upturned side of the belting, such side being disposed within the belting when the same is coinplete, as hereinafter described.

"When a wide belt, such :tor instance, :is si thirtjT inch beltt is being' mode, two of the belting sections shown in Fig. l?, which ser tions may be designated A, :tre disposed one over the other with theiiolded over edge sides thereof inwardly disposed. es shown 1n Figi 18, suoli sections being then sewed to gre-,ther to Complete the beltA lfVhe-n such wide belt being ma de by the machine the belting after emerging from the Jfeed-rolls GG posses over u conveyor apron 75, b v which it is czirried to the right or forward end of the mu chine into position to be token oli' onto u long table (not shown), which is provided tor supporting the sume. The conreyer apron 75 is `gjuided b v rolls TG. which are journeled at their ends in registering portions of side frames or standards TS. The forward roll (6. in the present instance. has sprocket wheel und chain :gfonnertion "(9 with o crosssh-.iit SO. which is iournzlled transversely of the 'trane l in suitable been reversing gear eonneetion, as "at 69, with the line-shaft 34, e leier TQ oonprinting iio tee

ings provided therein and -has one end in geared connection,.as at 81,'ivith the main shaft 84. A shift-lever 82 is provided for one of the gears S1 to shift the same into and out of engagement with its companion.

When a belt, which is half the Width 4of one of the belting sections A, is to be formed, such section after emerging from the feedrolls 66 enters a doubling trough 83, which .is mounted in advance of said feed rolls on a' table top or frame part 84 that isc'arried over the apron 75 by the standards 78. The trough 83 has its rear or inlet end of a Width substantially equal to that of the belt section A and the sides thereof converge to lgradually narrow and deepen the trough,

the outlet end of such trough having its sides quite close together and, of a depth substantially equal to the Width of one-half of a belt section A, as shown in Figs. 2 and-5. The belt section A is pressed at its center or along the longitudinal fold line thereof to the bottom of the trough 83 at or adjacent to its outlet end by a pressure Wheel 85, which is carried by a fork 86, the stem portion of which projects up through a superposed bearing 87 in a frame part 88. A coiled compression spring 89 encircles the stem portion of the fork 86 and serves to exert a yielding downward pressure onl the pressure Wheel. The frame 88 rises from the forward 'end portion of the frame part or standard 78 and forms bearings for a set of vertically disposed feed rolls 90, which are disposed in advance of the outlet end of the trough 83 with their bite in register therewith. The upper ends of the shafts carrying the rolls 90 have geared connection, as at 91, With a shaft 92, that is mounted in the upper portion of the frame part 88 transversely thereof and has one end in sprocketovheel and chain connection, as at 93, Figs. 2 and 5, with a shaft 94, which is suitably mounted in the lower portion of the frame 1 transversely thereof. The shaft 94 has geared "connection, as at 95, Fig. 6, with a main shaft 34, and one of suchl gears is shiftable into and out of mesh with its companion and controlled by a lever 96. The passing of a belt section A through the .trough 83 doubles the same into the form shown in4 Fig. 19 vand designated B. The sewing of the doubled over parts together forms a six-ply belt if a single illerstrip b is used, an eight-ply belt if two filler strips are used, and a ten-ply belt if three filler strips are used, as will be apparent.

Power for driving the shaft 34: is shown, in the present inst-ance, Figs. E?. vand 6, as beingl derived frein a motor 97, which is mounted Within the frame 1 and' has any suitable connection with said shaft as shown.

In theuse of my improved belt making machine vva strip a, of lany suitable material forfbelts' is fed from a roll or spool 2 lengthwise of the machine between the guide bars 8 thereof, being marked lengthwise thereof during such course of movement by one 0r more of the stylographic instruments 1l, and winding at the opposite end of the Inachine on a roll or spool 6. The spool 6 is thenmounted on the shaft which is journaled in the bearing arms 16 and the material a fed therefrom through spaced sets of feed-rolls 17, 17 and an interposed set of slitting knives 19, and the separate strips Z), which are formed by the slitting process, are then wound upon individual spools 2G, which are removably carried by the shaft which is joilrnaled in the bearing parts 97.'

lf a thirty inch belt section A is to be made the material strip a is sixty inches wide and is cnt into two strips, each of thirty inches width, or if desired the strip (L may be cnt into narrower sections for the making of narrow belts. If a belt section A is to be made with one filler strip b, only one of the spools 2G with a strip b thereon is mounted on a shaft in the frame part QG, the other fillermspool 9.6 being laid aside for subsequent-dise." lVhereas if the belt section A is to be provided-with two or more filler strips b the desired number of filler spools i6 are mounted on the shafts L18 for such purpose. A roll 50 containing a wrapping strip c of twice the width of the section A to be formed is mounted on the proper shaft 4-8 provided therefor and the strip c from such spool or roll and the strip or strips Z) from the spools 2G feed together between the feedrolls 52, and into the edge folding members 57, 57 with the strip or strips Z) disposed over the Wrapping strip c centrally thereof. As the strips and c feed together into the edge folding members 57 and through the guide 59 the side edge portions of the strip e are turned over the strip or strips with the edges thereof in substantial meeting relation and the whole is then pressed together in this folded form by passing between the feed and pressure rolls 6G, 66. If a belt similar to that shown in diagram in Fig. 18 is to be made the section lA after leaving the feed-roll 6G, 6G passes under the table 84 and is guided in its forwardcourse of movement by the conveyer apron 75.4 Vhcn two of the sections A have been made the same are placed one over the other in inverted relation and sewi-rdtogether, as indicated in Fig. 18. The purpose of marking the inner side of the sections A by' the printing cylinder 72 is to enable a manufacturer to identify his belt when returned for repairs or for other purposes. lf a belt similar to that shown in Fig. 19 is to be made a section A, after passing between the feed-rolls GG, 66, enters the folding trough 83 by which it is doubled `upon itself and thence passes between the pressure and feed rolls 90, 90, after which maaien folded form.

lf Wish it understood that my invention is not limited tov any specific construction or arrangement of the parts eXce t in so far as such limitations are speci ed in the claims.

Having thus described my invention, what I claim as new7 and desire to secure by Letters Patent, is,-

' l. In a belt making machine, edge folding means, and edge guiding means having a pendant web portion intermediate opposite side portions of said folding means, and flanges projecting outwardly in opposite drections from such web portion.

2. In abelt making machine, a pair of opposed edge folding members having overhanging or roof portions, and edge guiding means superimposing said portions and havmg an inverted T-shaped part depending therefrom with its arnis said overhanging portions.
